Clergyman, contemporary psychics, and even ancient prophets agree: The years 2009-2012 will mark the beginning of a cataclysmic end to life as we know it, paving the way for a stunningly different world on December 23, 2012.

According to Reverend Marc Clement, an ultra-conservative Belgian evangelist, there will be a nuclear war in 2011 resulting in several million deaths and almost incomprehensible devastation. He is sourcing his prediction from the Book of Revelation, which talks about the world disappearing in a “lake of fire.”

Derek Clontz, a herbalist, psychic, and futurist from Atlanta, Georgia, says the world will feel like it is ending by July 1, 2011 when political chaos causes the dissolution of the United States that results in a war with the Middle East.

Not all psychics believe that there is going to be an end of the world. In Sylvia Browne’s new book prophecy, she insists that the world will not end in 2012 and that we are not entering Armageddon. The only thing that she really predicts is that there will be an increase in skin cancer and breathing problems in children by 2013. She also predicts that acid rain will become a regular part of our weather ecology by 2024.

By the late 2020, she predicts that glaciers will melt and destroy the glaciers destroying coastlines and causing plagues and rivers of red due to flooding and tidal waves.A prophet of interest I found was in the book "Munich Playground" by Ernest R. Pope, published in 1941. Ernest R. Pope was an American newspaper reporter in Munich, Germany during World War II. This psychic accurately predicted the First World War. When it came to the end of the world he predicted a time of Universal Killing followed by a time of Universal Dying from starvation and disease. He also predicted a “White King” who would bring peace on earth.

Scotland Prophet Coinneach Odhar, the Brahan Seer, of the 1600s wrote many end of the world prophecies. His ominous prophecy for the future of Scotland is "black rain” that exterminates the people and animal life in Scotland. No date is predicted for this. Possibly this could be nuclear fallout in Scotland from World War 3?

Jean Dixon was an American psychic and writer, whose prophecies were followed with interest by the American public from the 1960s into the 1980s. She is well known for her prophecies to do with the antichrist.

She had a vision that on February 5, 1962, a child was born in the Middle East, who would transform the world by year 2000, creating a unifying world religion, and bringing world peace. She saw a cross growing above this man, until it covered the whole earth. This child was a descendant of the very beautiful Egyptian Queen Nefertiti and her Pharoah husband Amenhotep IV, or Akhenaten, an "enlightened" pharoah, who created a monotheistic sun-worship religion. This was to be a great leader that saves the world from Armageddon.

Also mentioned in "A Gift of Prophecy" is a Jean Dixon vision on July 14, 1952. Jean saw a vision of a large snake that was a very wise snake; its eyes were looking toward the East, with great wisdom. She felt that this snake knew all things. The snake told her that she too must look to the East for wisdom. And she felt that this snake was a bringer of peace on Earth and good will and great knowledge. Some scholars say that the snake was warning of the arrival of the Anti-Christ.

There are also the prophecies of John Titor, who claimed to be a time traveller from the future). He posted his messages about the future and time travel on the web. He said he lived in Florida in 2036. He predicts a civil war in the United States in 2012 and then a World War in 2015 that results in 3 billion deaths. The reason that this psychic was paid attention to is that he made many correct predictions about mad cow disease in the 1990s.

Miriam Ponder-Hulett is another new generation prophet and psychic. This British visionary predicted the death of Princess Diana. She has made some very dire predictions including that the hole in Earth's ozone layer quadruples in size, exposing virtually the entire Southern Hemisphere to lethal levels of ultraviolet radiation. This frying of the populace will cause the mass migration of more than a billion people north. Cities that once were comfortably populated will be crowded and starvation and shortages will be the norm.

She also predicts that a nuclear arms test in India will go wrong resulting in a massive underground explosion that leaves a crater the size of Denmark and kills an estimated 55 million people.

There are also the prophecies of Mitar Tarabich, a peasant who had visions of the future, who lived in Serbia from 1829 to 1899. He predicted widespread environmental damage across the world, with the air and water supplies poisoned. In the country, away from the cities, people will take refuge in the "mountains with three crosses" where there will be fresh air and water. Then a worldwide famine will occur that kills billions.

According to Nostradamus, a doomsday comet will split the moon in two by 2012. Some scholars of Nostradamus say that this has already happened and that the quatrain about this is to be interpreted as the bringing back of the moon rocks from the moon in the 1960s.

Not all psychics believe the end of the world is going to be on 2011. According to Biblical scholar and psychic Harold Camping (who hails from Oakland, California), the world is going to end on May 21, 2011. This prediction is also based on a mathematical calculation based on the passage of timelines in the Bible.
